Integrated Controls

Maximize your savings and comfort.

Integrated controls automatically switch between a heat pump and fossil fuel heating system at a pre-set outdoor temperature. This allows you to minimize the use of a boiler or furnace while maximizing the use of a heat pump to provide maximum savings and comfort. Receive up to $1,500 when you install an integrated control to an existing heat pump system.
